  • Two locations of gacutil.exe

    - by bmw0128
    I'm developing on Windows 2008 R2 Server, 64 bit. I'm learning how to use gacutil.exe I found two copies of this file: C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\x64 C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bin\ I built a dll in VS2007, then I added a build post event, that calls gacutil.exe to transfer the dll to GAC. Does it matter which gacutil.exe I use?

  • .NET RegEx "Memory Leak" investigation

    - by Kevin Pullin
    I recently looked into some .NET "memory leaks" (i.e. unexpected, lingering GC rooted objects) in a WinForms app. After loading and then closing a huge report, the memory usage did not drop as expected even after a couple of gen2 collections. Assuming that the reporting control was being kept alive by a stray event handler I cracked open WinDbg to see what was happening... Using WinDbg, the !dumpheap -stat command reported a large amount of memory was consumed by string instances. Further refining this down with the !dumpheap -type System.String command I found the culprit, a 90MB string used for the report, at address 03be7930. The last step was to invoke !gcroot 03be7930 to see which object(s) were keeping it alive. My expectations were incorrect - it was not an unhooked event handler hanging onto the reporting control (and report string), but instead it was held on by a System.Text.RegularExpressions.RegexInterpreter instance, which itself is a descendant of a System.Text.RegularExpressions.CachedCodeEntry. Now, the caching of Regexs is (somewhat) common knowledge as this helps to reduce the overhead of having to recompile the Regex each time it is used. But what then does this have to do with keeping my string alive? Based on analysis using Reflector, it turns out that the input string is stored in the RegexInterpreter whenever a Regex method is called. The RegexInterpreter holds onto this string reference until a new string is fed into it by a subsequent Regex method invocation. I'd expect similar behaviour by hanging onto Regex.Match instances and perhaps others. The chain is something like this: Regex.Split, Regex.Match, Regex.Replace, etc Regex.Run RegexScanner.Scan (RegexScanner is the base class, RegexInterpreter is the subclass described above). The offending Regex is only used for reporting, rarely used, and therefore unlikely to be used again to clear out the existing report string. And even if the Regex was used at a later point, it would probably be processing another large report. This is a relatively significant problem and just plain feels dirty. All that said, I found a few options on how to resolve, or at least work around, this scenario. I'll let the community respond first and if no takers come forward I will fill in any gaps in a day or two.

  • Programmers - I have a question for you.

    - by jens
    My boyfriend does coding (Rails/C?/PHP) for a job and I don't know what he would appreciate on our first anniversary. Does anyone have any ideas? Yes, he's stereotypical geek, but I'd rather not give a pack of Bawls for an anniversary gift. He dislikes going anywhere, so "experiences" like going to an event are out. Maybe I should just have a giant LAN party in the house.

Thanks!

  • Validating String Characters as Numeric w/ Pascal (FastReport 4)

    - by user2525015
    I'm new to Pascal and FastReport. This question can probably be answered without knowledge of FastReport. Pascal is Delphi. FastReport4. I have a text box accepting an 8 character string as input. Each character should be numeric. I'm attempting to validate each character as numeric. I've tried using the val function... Procedure Val(S : String; var R: Real; Code : Integer); begin end; procedure thisinputOnChange(Sender: TfrxComponent); var S : String; error : Integer; R : Real; begin S := thisinput.lines.text; Val (S, R, error); If error > 0 then Button2.enabled := False; end; I got this code online. The explanation says that the function will return an error with a code greater than zero if the character cannot be converted to an integer. Is that explanation correct? Am I misinterpreting? Right now I am trying to set a button's enabled property to false if the validation fails. I might change that to a message. For now, I would like to get it to work by setting the button property. I'm not sure if I should be using the onChange event or another event. I'm also not sure if I need to send the input to the val function in a loop. Like I said, I'm just learning how to use this function. I am able to validate the length. This code works... procedure thisinputOnChange(Sender: TfrxComponent); begin if length(thisinput.lines.text) = 8 then Button2.enabled := True; end; Any suggestions? Should I use the val function or something else? Let me know if I need to provide more info. I might not be able to check back until later, though. Thanks for any help.

  • How to extract files from Windows Vista Complete PC Backup?

    - by Martin
    Is there a program or API I can code against to extract individual files from a Windows Vista Complete PC Backup image? I like the idea of having a complete image to restore from, but hate the idea that I have to make two backups, one for restoring individual files, and one for restoring my computer in the event of a catastrophic failure.

  • Error Connecting to Third Party App via COM: mscorlib Exception from HRESULT: 0x80040202

    - by Dave
    One particular user is getting an exception when connecting an application I created to a third party app using COM. The connection fails with the following error: Source: mscorlib Message: Exception from HRESULT: 0x80040202 This software works fine for other users. Any ideas what could be going on? The error occurs just before the app adds some event handlers to some of the COM objects from the third party app. It is able to successfully instantiate the objects, though.

  • Safari/Chrome problem with ajaxsubmit?

    - by Jan
    Hi I'm currently having some weird issues with ajaxsubmit (http://jquery.malsup.com/form/#ajaxSubmit), which I'm currently using in a project. I have a flow where I need to open a form into a modal window. I'm using fancybox for that and it works like a charm. When the form has been forced to open in the fancybox window there can happen two things. 1) If the user who is about to submit the form is logged in she should see a confirmation in the modal box, that her input was succesfully submitted 2)If the user is not logged in there should be loaded a login form once she hits the submit button 2.1) When the user has logged in she should receive a confirmation in the modal box. This is also working like a charm in Firefox, IE8 and IE7 but not in Safari or Chrome. The weird part is that it seems like safari and chrome are completely ignoring my ajaxsubmit form. To force the first form to be opened I use the follwoing script - this part is working in both Safari and Chrome. $(".klikEnPrisForm").ajaxForm({ success: function(data){ $.fancybox({'content':data}); } }); My ajaxsubmit form scrip looks like this var options = { url: '/?altTemplate=XmlProxyKlikEnPris', dataType: 'xml', data: $(this).serializeArray(), success: function(data) { if ($(data).find('loggetind').text() == 'true') { $("#klikenpris").hide(); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/KlikEnPrisAccept?tilKvittering=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } else { $("#klikenpris").hide(); $("#fancybox-wrap").css({ 'width': '480px', 'height': '220px' }); $("#fancybox-inner").css({ 'width': '460px', 'height': '220px' }); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/login.aspx?loginklikpris=0&klikpris=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } } }; // bind to the form's submit event $('#klikenprisform').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); I have tried inserting an alert in the succes callback function but it's never being called it seems. It seems like the default action is not being overruled by the link written in the "url" in ajaxsubmit. I'm really puzzled about this, since it's working nicely in other browsers and I'm completely lost on how I should approach the debugging in safari/chrome. I hope all the above makes sense and I'm looking forward to hear any suggestions. Cheers!

  • jQuery Dialog causing buttons not to post-back

    I'm using the jQuery UI Dialog() function on an ASP.NET webform, on a particular panel. After Dialog() is applied, the buttons become useless and will not post back at all; I'm not even getting a Page_Load event firing, let alone any button events. Is the Dialog function messing with my button events? If so, is there a way to fix this?
